LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 360,984. dated April12, 1887. I 'I vApplication tiled August 10, 1886. Serial No. 210,530.(No model.)

To all whom it may concern.-

Beit known that I, LEwIs J ArwocD, of Vaterbury, in the county of NewHaven and State of Connecticut, have invented an Improvement inLamp-Burners, of which the following is a specification.

This invention is made with reference to that classof burners in whichVtwo wicks are employed and in which the chimney-holder is adapted tobeing raised or lowered.

In my improvement the. slide-rods that support the chimney-holder arebetween the two wick-tubes, and slide through openings in theratchet-cap and burner-base, and the spring that supports the slide rodsand chimneyholder is nearly straight and passes across the middle of theburner above the air-distributer, and its ends are firmly fastened tothe burnershell, so that the springcannot become detached or injured,and there is a pusher to unlatch the spring from the slide-rods to allowthe burner to descend.

In the drawings, Figure 1 is a vertical section of the burner with thechimney-holderin an elevated position. Fig.v 2 is a plan view 0f theparts below the line m w. Fig. 3 is an inverted plan of the globe-holderand parts connected therewith; and Fig. 4 isan elevation of thesliderods, part of their supportingspring and the bridle-piece detached.

The base of the burner is made as a screw, 2, and above the same themetal spreads outwardly, and is perforated at 3 for the passage of air,and at 4L is the top flange of the base, anda rim, 5, around it.

The ratchetcap 6 covers the ywick-raisers 7 and 8, and it is perforatedfor the passage of the tubes 9 and 10 for the wicks, and 1l is aforaminous air-distributer resting on the flange 4,andthese parts areall permanently connected together. Y

The chimney-holder 15 is usually made with springs to grasp the base ofthe chimney, and within the same is the deflector 16, with flameslotsabove the wick-tubes, and around the chimney-holder is an open gallery,17, for the shade or globe, and the inwardly-projecting arms 18 arefastened at their outer ends below the gallery and at their 'inner endsto the ver-A tical sliding guide-rods 20, that pass through holes in theair-distributer, the ratchet-cap, and the burnerbase, and at their lowerends there are projections or heads that prevent the chimney-holderbeing raised too high.

There is a spring, 21, crossing over the airdistributer between the twowick-tubes, and the ends are bent at right angles and riveted to theinner surfaces of the rim 5, and this spring presses against the slidingguide-rods 20 at one side thereof, so as to spring into the notches insuch guide-rods and hold up the chimney-holder when it is elevated abovethe tops of the wick-tubes; y

In order to lower the chimney-holder there is a bridle-piece, 25,attached to the spring and passing around one of the wick-tubes to nearthe inner surface of the rim 5, and the push-pin 26, passing in througha hole in the rim, is attached to the bridlepiece, and by these thespring is pushed back to unlatch the sliding guide rods and allow thechimneyholder to be lowered.

The parts are compact and strong and are not liable to become bent inuse, and the wicks h are easily trimmed or lighted.

When the chimney-holder and gallery are lowered, the latter rests uponthe top of the rim 5, as seen in dotted lines, Fig. 1.

I am aware that the chimney-holder has been held upon sliding guide-rodspassing through the burner-base'and ratchet-cap, as in the patent No.34,065, to T. Mayhew, and also that a revolving nut has been used toraise and lower the rods and chimney-holder, and that springs have beenemployed for sustaining the chimney-holder when elevated. In myimprovements the spring, being nearly straight and attached at its endsto the burner, is not liable to be bent or injured, and is much lessexpensive to manufacture than the devices heretofore employed, and theparts are simple and durable.

I claim as my invention-'- 1. The combination, with the burner-basehaving the screw and perforated portion, and the ratchet-cap andair-distributer and the two wickftubes passing through the base,lratchetcap, and air-distributer, of vertical guide-rods passing inbetween the two wick-tubes down through the air-distributer,ratchet-cap, and

rco

burner-basc, and the chimney-holder fastened to the upper ends of theguide-rods, and a spring-catch attached at both ends to the burner andacting to hold the guide-rods when ele- 5 Vated, and a pusher and forkedbridle passing at each edge of one of the wick-tubes and attached at itsends to the spring, substantially as set forth.

2. The combination, in a lamp-burner, of [o two wick-tubes7 aburner-base with a rim at its upper edge, a ratchet-cap andair-distributer, two vertical guido-rods passing down through theratchet-cap and burner-base, and a chimney-holder attached to theguide-rods, and a I 5 deflector carried by the same, a nearly-straightspring passing across the burner between the wick-tubes and attached atits ends to the rim and pressing against the sides of the guiderods7 anda pusher to move the spring, sub- 2o stantially as set forth.

3. The combination, in a lamp-burner, of two wick-tubes, a burner-base,a ratchet-cap and air-distributer, two vertical notched guiderodspassing down through the ratchet-cap and burner-base, and achimney-holder sup- 25 ported by the guide-rods and a deiector carriedby the same, a nearly-straight spring passing across the burner betweenthe wick-tubes and attached at its ends to the burner-she117 andpressing against the sides of the guidc- 5o rods, and a pusher tounlatch thc spring, substantially as set forth.

Signed by me this 5th day of August, 1886.
